PORTABLE ELEVATOR.

SJEIEGIFIGATION forming part of Letters Patent No. 682,224, dated September 10, 1901.

` Application filed March 2, 1901. Serial No. 49,639. (No model.)

To all whom, t may concernf Be it known that I, WALTER L. NICHOLSON, a citizen of the United States, residing at Edholin, in the county of Butler and State of Nebraska, have invented a new and useful Portable Elevator, of which the following is a specification.

Thisv invention relates to improvements in portable elevators; and one object is to pro- 1 vide a simple construction of elevator which may be conveniently transported from place to place and by means of which grain or other matter may be elevated to theB granary or other place where it is desired to store the same.

Another object isto provide the elevator with means for elevating one end of a wagon for the purpose of dumping the grain therefrom.

A further object is to provide an improved construction for reversing the movement of the swinging boom, whereby it may deliver the bucket or box to either the right or left of the elevator.

With these objects in view the invention consists in the novel features of construction hereinafter fully described, particularly pointed out in the claims, and clearly illustrated by the accompanying drawings, in which- Figure 1 is a side elevation of an elevator constructed in accordance with my invention, 'a wagon being shown in position upon the platform thereof and elevated at one end; Fig. 2, a top plan view with the wagon re- 1 moved; Fig. 3, a vertical sectional view; Fig.

4, a similar View at right angles to Fig. 3; Fig. 5, a detail of the wheels for operating the winding-shaft, showing the clutch mechanism for locking the same thereto and releasing them therefrom; and Fig. 6, a det-ail of the grain-elevating box or receptacle.

Referring now more particularly to the accompanying drawings, A designates a platform supported upon suitable runners B, extending longitudinally thereof and at its side edges and provided at its ends with hinged inclines C, which may be swung upwardly when the elevator is transported from place to place.

D designates uprights which are pivoted at their lower ends to the inner sides of the runstandards, as illustrated.

ners B, the same extending upwardly through suitable openings `in the platform. These uprights are arranged in pairs, and pivotally attached to the standards of the several pairs are longitudinally-extending bars E, which are disposed intermediately the ends of the The standards of the several pairs are connected at their u pper ends by longitudinally-extending bars F, which are pivotallyattached thereto, and connecting said longitudinal bars F are crosspieces G. Thus a framework is provided at each side of the platform, which frames are 1 connected at their upper ends by cross-pieces.

The pair of standards at one end of the platform and the pairintermediate the ends there- Vof have blocks or guides H secured on their opposite sides and between which they move when swung upon their pivots. For holding the standards or uprights in a vertical position swinging braces I are provided, which are pivotedv at their lower ends to the platform and at their upper ends formed with hoooks to engage eyes carried by the central pair of uprights. By disengagin g said braces the framework may be swung longitudinally of the platform to lower the height of the elevator, so that the same may pass through low doorways of barns or other outbuildin gs where it is desired to store the same.

The platform near the standards at the other end of the elevator is cut out to form a space, receiving a movable section J for elevating one end of the wagon. This movable section when in its lowered position rests in said opening and is iiush with the platform. Said movable section has its ends recessed to receive the standards, upon which it m oves vertically,and is provided with cleats K, which engage the front wheels of the wagon and prevent the latter from moving from the platform when the forward end thereof is elevated. Elevating-ropes L are secured to said movable section at its respective ends and pass upwardly around pulleys M, mounted upon the inner sides of the standards, and are attached at their upper ends to drums N upon a shaft O, extending transversely of the platform and mounted at its ends in suitable bearings P, carried by the standards. Upon said shaft O is a chain or sprocket wheel Q, around which a chain R ICO l passes, said chain passing around a sprocketdrawn upon the platform and the horses released therefrom.

Centrally pivoted at its inner end upon the central-cross-piece at the top of the frame is a boom U, having at its outer end a vertically-disposed pulley U. Mounted upon the longitudinally-extending'bars F at the upper ends of the standards are pulleys V, which are positioned upon the respective sides of the boom and are disposed at an angle. Secured to the under side of the boom intermediately of its ends are ropes W, which pass over pulleys V, and at their opposite ends are adapted to be oppositely wound upon pulleys X, mounted upon a shaft X', extending transversely ofthe platform and supported in suit- 4 able bearings carried by the central pair of uprights or standards. Upon this shaft is a drum Y, upon which the elevating-ropes Y are wound, said ropes passing over a pulley Z, supported upon the central cross-piece and'in rear of the swinging boom, and over the pulley U at the end of said boom. These ropes are held separated upon the boom by the raised portion a, which is disposed centrally of the boom and extends longitudinally thereof, the ropes being positioned upon its opposite sides. For rotating vthe shaft in order to wind the elevating-.ropes upon the drum I provide two wheels or drums b, which are loose thereon, but either of which may be locked thereto by mechanism presently to be described. Secured to each of said dru ms b isa rope c, said ropes extending in opposite directions upon the drums and extended f downwardly to the platform, where they pass around'a pulley cl. The horse is attached to either of these ropes, according to the direction in which it is desired to swing the boom.

By. drawing upon one of the ropes the shaft is revolved in one direction, winding the clevating-ropes thereon and at the saine time winding one of the ropes W and unwinding the other, so as to swing the boom at the same time that the grain is elevated.l By drawing upon the other rope the opposite rope W is wound upon its pulley X and the boom swung to the opposite side of the elevator. Each of the drums is formed on its inner side and at its center with a plurality of radially-extending depressions e, and extending transversely of the shaft is a pin or projection f, which is disposed between the two drums or wheels. An operating-lever g is provided, which when moved in one direction moves one ,of said drums with one of its radial notches or recesses into engagement with the pin carried by the winding-shaft, so that said drum is locked thereto, while a reverse movement of said lever releases said drum from the shaft and locks the other drum thereto.

Ropes V are secured at their lower ends to an elevating box or receptacle h, having al flaring top t and slides j, controlling outlets in its side Walls. These slides are moved to 'open the outlets by suitable cords or ropes 7s.

'same is elevated by the horse, the receptacle being at the same time swung laterally of the elevator, so that the grain may be delivered to the granary. Vhen in proper position', the rope operating the slide is drawn upon, opening the outlet and permitting the grain to discharge into the granary.

While I have described my invention with particular reference to its use as an elevator for grain and for use about the farm, where it is particularly convenient, yet I do not limit it to employment in that connection, as it will be found useful wherever a simple and effective construction of portable elevator is desired.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

vl. An elevator comprising a support provided With a vertically movable section, means to elevate the latter, a framing carried by the support, a boom mounted upon the framework for swinging movement, a receptacle suspended from the boom, and mechanism for simultaneously swinging the boom and elevating the receptacle, substantially as described.
